Redstone Computer Schematics

A redstone computer is built from the same logic gates as any other circuit, combined into larger parts: adders that add binary numbers, an arithmetic logic unit (ALU), memory that stores bits, and displays made from redstone lamps. Even a simple adder is a good way to see how binary arithmetic works.

Computers are large and timing-sensitive, so build them with Litematica's layer view and test each section as you go. Redstone dust carries a signal 15 blocks before it needs a repeater, which shapes how these machines are laid out. Redstone behaves differently in Java and Bedrock Edition, so check the edition and version on the schematic page before you build.
